Oklahoma trails · Yellow Trail (Lake McMurtry Park)
A 5.0-mile network in Oklahoma, with 64 ft of climbing. Reaches Lake McMurtry.
The climbing leans toward the final third: 50% of the ascent falls between mile 3.3 and mile 5.0. It gives back about 163 ft along the way, so it rolls rather than climbing steadily.
